Questions about PX7 Markdown Viewer

What is PX7 Markdown Viewer?
A free native Mac app that renders Markdown files, adds Finder Quick Look previews, and lets you edit and save the source. All local.
Where does PX7 Markdown Viewer do its work?
PX7 Markdown Viewer works directly with the Markdown files stored on your Mac.
How much does PX7 Markdown Viewer cost?
PX7 Markdown Viewer is free. It has no subscription.
Which Macs can run PX7 Markdown Viewer?
macOS 14 or later
How do I preview Markdown files in Finder?
Install a Quick Look extension and pressing Space on a .md file renders it instead of showing the source. PX7 Markdown Viewer adds that preview and also opens .md files on double-click.
Why does Quick Look show raw Markdown text?
macOS has no built-in Markdown renderer, so Quick Look falls back to plain text and you see the asterisks and hashes. A Quick Look extension replaces that fallback with a rendered view.
Can I edit a Markdown file directly from its preview?
Yes — ⌘E switches to the source and ⌘S saves it, so a small correction does not need a separate editor. Images are resolved from the note's own folder.
Is there a free Markdown viewer for Mac?
PX7 Markdown Viewer is free. It renders CommonMark and GitHub-flavoured Markdown, runs entirely on your Mac, and needs no account.
